I really don't think I have seen a better drill sharpening video. Well described in detail with no fluff. Thanks so much!

@cwrobinson6363 7 лет назад

I like how clear the camera video was in this RU-vid. This makes it easy to understand. THANK YOU.

@MrJurheealan 11 лет назад

Awesome video! I'm a union carpenter in Chicago and have used drill bits daily for over 25 years. It's great to know the RIGHT way to sharpen a drill bit!! Well done and thanks so much!!

@shaddowgraham 12 лет назад

WELL WELL WELL About time someone came up with a video to explain how to sharpen drills, , THANKS, the thing that makes your's 1000% better than the rest is the clear explanation and most important the different angles. Thanks a lot

@psiconsultorio 10 лет назад

Barry, it´s the most professional tutorial i´ve seen on the matter. Thanks a lot for sharing your experience with all of us.

@herminigildodelacruzjr1752 4 года назад

Very clear tutorial of all that I've seen in RU-vid thanks for sharing i hope that you never get tired of sharing your knowledge great video

@dumonr71 11 лет назад

I've been looking at a lot of videos on bit sharpening and this was probably the easiest to understand. Thanks!

@gypsymagic1962 11 лет назад

Very good video well presented and filmed... Now after 20 years of buying new drill bits and wondering how to do this,I now know how... Thanks...

@rondumontier1187 6 лет назад

Finally!!! A proper bit sharpening tutorial. Congradulations on your very good effort. 👍👌😎

@georgecarra 11 лет назад

you my friend are a MASTER of teaching. I sing my praises to you Sir.

@DennisChaves 13 лет назад

I just want to thank you guys at Projects in Metal. I actually work in a machine shop, operating CNC machines. I've been in the machining trade for almost 5 years now but I have NEVER understood how to properly sharpen a drill. I think I get it now! The problem I've had jumping into work without any formal training is I don't know how to do things like this and no one has the patience to teach me while they're busy doing their job. Tomorrow I'll take a stab at it.

@NMranchhand 7 лет назад

That was beautifully presented; pace, detail level, reasoning; outstanding, a pleasure to watch.

@OldSneelock 12 лет назад

Well done. When I saw Part 1 I thought "Oh no another sales pitch." In Part 2 you have clearly explained the thinking behind the method. I noticed that the chipped drill you sharpened had the web thinned. Will you be showing how that is done? Since I use home shop equipment now I find that reducing the web on 1/4" up to 1/2" bits allows me to make one pass holes even with reduced power machines.

@mlminto 11 лет назад

Excellent video! I have been struggling with sharpening my own drill bits, and I believe your instruction will help me in this learning process - thank you!

@caseyreep1794 Год назад

I have watched alot of drill bit sharpening videos, and this is by far the best. Took my sharpening skills to a whole new level.

@mjb12141963 8 лет назад

WOW! I have been trying too hard. I have been trying to twist the drill as I raised it to grind the heel and they keep coming out multi-faceted like the it was to begin with. Thank you for making it so clear.

@ProjectsInMetal 11 лет назад

Thanks for the feedback. I think Barry rounds off the clearance lip just because it makes it look nice and finished. He mentions in the video that you don't want facets. Facets don't really hurt anything (at least not anything that I can think of), they just look bad.

@tubergenmotorsports4193 8 лет назад

Thank you sir! Nice to see it done correctly, before I go off and destroy all of my bits. I still have to order a good gauge.

@ProjectsInMetal 12 лет назад

You're welcome Graham. It was a fair amount of work to edit all those angles together. So I'm glad to hear that you appreciate the multi-angle vid!

@devers6 13 лет назад

Greetings from a fellow Seattleite! This was a very helpful video; I will have to try it myself. I have a drill doctor, but I have always wondered how to do it by hand. Now if you ever want to do a video on sharpening end mills, I would be the first to watch it.

@markusbFPV 13 лет назад

Thank you! Have tried this before but never got good result. Now it works much better. Always missed grinding the heel of..

@hullsmillfarm 13 лет назад

Brilliant instructive video. your attention to detail is very good, i'm gonna bet you've taught before... i have seen large bits sharpened when working in an engineering factory, looks easy until you try without being shown. Thank you.

@Jamie-xm1zj 10 лет назад

Think you really good at explaining flawless techniques

@NMranchhand 11 лет назад

Clean, clear instruction. Thanks very much.

@ChevySS1968 8 лет назад

Great vid, thanks. I particularly like the close-up shots. Those are difficult to keep in focus, but you did a good job....thanks

@stevendavis6759 Год назад

Excellent video where can I buy the angle gauge that you used. What is the brand name of it and model number.Thanks for sharing!!!

@muhaahaloa941 8 лет назад

Wow you make it look very easy :) Tried today on a 20mm drill bit ended up with about 20 facets..Going to have to keep watching and trying.

@lukemain4222 7 лет назад

Muhaa Haloa It could be because your wheel needs dressed as mine does :) That can make it a lot harder. I dont know where the heck my dresser went. He's got an ideal set up with that nice sturdy rest and wide wheel. The one I use is only 1" thick and a flimsy rest.

@SirRootes 10 лет назад

Thanks for taking the time to make the video. Very informative. Thank you. ;)

@ProjectsInMetal 11 лет назад

You're welcome. I'm glad you found the videos instructional and helpful. Now you don't have to buy new drills! Although I still buy replacement small drills (under 1/8") because they are a pain to sharpen. But they are cheap, so I don't worry about resharpening them, or I use a drill doctor.

@MaxwellForce 9 лет назад

Very nice instructions. And very informative. Cant wait to try it out my self. Thanks

@dangitification 11 лет назад

Thanks for this info. I have been sharpening my larger bits for some time, with fairly good results. But I didn't know there was a gauge for measuring the length of the cutting edge. I just do it by eye. I'll have to get one of those drill point gauges.

@hchinchilla1 9 лет назад

Thanks for the great demonstration. Insights were very helpful.

@macmac369 11 лет назад

Wow! U explained everything so clear and i really enjoy this video clip. From now on, I will sharpen my drill bits in your way. By the way, what should be the grit of your stone for sharpening? I ask bcoz mine is very coarse but yours seems very fine one.

@MegaLostOne 3 года назад

There is another trick with that gauge I never see used or mentioned. The point of the bit across the web there will be an angle, if you lay the gauge across the cutting edge the angle across the web should be close to the angle of the gauge so the point can push material out of the way, If the angle across the web is to straight it won't push metal out of the way and the tip of the drill bit doesn't want to cut.

@clydegalt5121 4 года назад

I can't see well but it looks as if your sleeve comes close to the grind wheel. Would it be better to not reach across by moving your cooling water to a stand or something?

@ntutfitness 3 года назад

Nice and thanks! Learning a lot from your video.

@youngcameracompany 13 лет назад

@detvardasatanme If you don't grind the heel away the drill will not penetrate. Glad you found the video helpful. Barry Young

@ProjectsInMetal 13 лет назад

@detvardasatanme Glad the video helped! Grinding the heel is critical. You don't need to grind a lot away, just enough so that the heel doesn't interfere with the cutting action of the lips. We remove quite a bit of the heel in the video, more than is necessary. But we did so to illustrate the process.

@ProjectsInMetal 11 лет назад

Excellent! Glad you liked the videos.

@88ueshiba88 4 года назад

Great vid, really helpful and clear! Apreciated a lot, thanks!!

@ProjectsInMetal 13 лет назад

@0x1 Well, it's been a day, how did it go? Did you get a chance to try your own hand at sharpening? In any case we are glad you liked the videos! Good luck on learning to sharpen your own bits. It's really not that hard once you get the hang of it.

@youngcameracompany 13 лет назад

Maybe once I get the Quorn built, I will do just that. Thanks for your kind comments. Barry Young

@HollerboyHellbilly 9 лет назад

first american instruction video i watch that tells me to wear protective gear! Great vid btw ^^

@BoldUniverse 11 лет назад

Excellent advice, love your technique.

@rudyrosales2257 7 лет назад

Great video. Thank you for making and sharing!

@Majorvideonut2 9 лет назад

That was very clear. I now understand why the heel is ground also

@mjb12141963 9 лет назад

Now all I need is a workbench, a grinder and a measuring tool. What is that one called?

@timtynan2787 6 лет назад

finally someone sharping a drill on youtube

@ProjectsInMetal 12 лет назад

That's true, long sleeves can be dangerous in the shop. I generally wear short sleeve carhartt shirts and (if it's really cold) a carhartt vest. It's safer to heat the shop than it is to wear long sleeves. However, I'm not generally worried about long sleeves around the grinder. I'm more worried about them around the lathe, mill, or any other machine with rotating parts that can snag the sleeves.

@ProjectsInMetal 11 лет назад

Happy to help!

@bigjano 11 лет назад

Thank you very much. Greetings from Chile.

@CMAenergy 5 лет назад

That's the way I was shown many long years ago. probably before you were born, an then you get some guys telling you you have to do it on a flat wheel But with the side of a flat wheel you never get an even cut, But don't explain that to these young guys, they know it all. I been trying to find a drill gauge for quite a while, so where can I get one in local stores,

@fall22123 12 лет назад

Wow nice job. The drill looked good. Long sleeves in a machine shop = bad...especially when working with stuff like grinders and drill presses.

@jimm2442 6 лет назад

Excellent video, Thank you!

@benparkin7884 8 лет назад

if you want a quick measuring tool you can put two nuts beside eachother, itll be a 120 included angle but thats probably close enough for you if you have to use that trick! also you didnt cool it enough you can see at the end you lose the temper on the cutting edge that bit will dull quickly

@alfredoeduardo1974 11 лет назад

It is also necessary to mention that it is a must to use a steady and sturdy bench grinder, cheap ones will vibrate and won´t perform correctly.

@ProjectsInMetal 13 лет назад

@hullsmillfarm Barry is indeed an instructor at Bates Technical College in Tacoma WA. I started a machining website for beginners (link in video description) after taking night classes from Barry. It quickly became apparent that video tutorials would be very helpful to my visitors so we decided to work together to produce these videos. I'm glad you found the video helpful. Be sure to subscribe to the ProjectsInMetal channel, we have more videos coming soon!

@adanlopez1077 5 лет назад

Gracias very professional

@AstraWerke 11 лет назад

Thanks so much for this tutorial - helped a lot!

@ProjectsInMetal 13 лет назад

@devers6 Glad you found the video helpful! I have a Drill Doctor as well, but this technique is still useful to master. For one thing, you can use it with drills that are too large for your Drill Doc, and for another, you can use the skill to impress your machinist friends! Sharpening end mills by hand? I wish I was that skilled! However, we may be reviewing an end mill sharpening machine down the road, so be sure to subscribe or check back often.

@ajchien 11 лет назад

Can you show us how to grind a split point tip in a future video?

@JimPoorBlacksmith 11 лет назад

@ProjectsInMetal 11 лет назад

I'm pretty sure the wheels are aluminum oxide. They are old (they are huge so they haven't been replaced in years) so I'm not positive. If you're grinding HSS drills aluminum oxide works well. If you're grinding carbide drills you'll need a silicon carbide ("green") wheel.

@JaakkoF 11 лет назад

Nice videos, but you can't determine the proper clearance angle from looking at the side of the drill, as you are looking at a curved surface, so it is more of a compound angle. Easiest is to look at your chisel line angle in relation to your cutting edges, it should be around 120-135 degrees. Also, you didn't have to grind that rounding off, you could have ground the tips of the cutting edges with a primary clearance angle, makes it last longer and makes a smoother and more round hole.

@powershop1903 12 лет назад

Ever scribe a line on the grinder tool rest? 59 degrees

@alfacor27 11 лет назад

nice grinder very informative

@DennisChaves 13 лет назад

@recidex harbor freight sell them. they call it a "multi-use rule"

@honeybunchickens 11 лет назад

perfect video man thank you

@ProjectsInMetal 11 лет назад

That's not a bad idea. I've used a sharpie to mark a temporary line on the grinding rest, but I've never scribed a line.

@adrinvaldez3038 9 лет назад

thank you for the video....i learned a lot...

@HHHHKGIK 11 лет назад

just wondering why you dont use a starrett drill point gage

@David-yg8tf 10 лет назад

That's why I don't use grinding stones. SANDING WHEELS are the best choice. The bits comes out perfect. 2nd best choice is a diamond wheel - which I don't own yet. Old timers love stones.

@oppositeworlds1460 9 лет назад

Thank you for this explanation. Would you please tell me what the right angle is?

@lukemain4222 7 лет назад

Opposite Worlds The total angle is 118° meaning each flute should be 59°. I can't believe nobody answered that in a year. What jerks :)

@oppositeworlds1460 7 лет назад

Thank you.

@Pasdechevredreamer 10 лет назад

Good effort. Thanks

@lamarl9978 7 лет назад

Long sleeves was a NONO in our shop.

@gregwilson9035 5 лет назад

At 3:20 I thought his sleeve was getting too close the wheel.

@TheHumanNacho 10 лет назад

@what1864 6 лет назад

i can get my drills sharp and cutting correct size hole, but they walk on the metal afterwards , when new they didn't

@hooperwille 11 лет назад

my drill bit had like a small snake tongue at the tip, how do I replicate that shape when sharpening?

@paingivernight 12 лет назад

That was great!

@ProjectsInMetal 12 лет назад

Thanks everyone for your continued interest and positive comments. It's nice to wake up to friendly comments in my email inbox! It keeps Barry and I motivated to keep making videos.

@henrikaize 7 лет назад

why he didn't demonstrate the drill bit to drill before and after sharpened

@joehindley823 11 лет назад

davs have augers. if i ground a drill that made curly chips it clogs the auger and the machine fills with chips and its smash-up time lol by changing the angle on the cutting edge you decide by negative or positive what chips to make. nagative angle makes broken up chips. positive angle makes curly chips which is ok for acme or tri-ways, no good for davs.

@doyouwanttofuk 11 лет назад

how come you didn't thin the web, it looked to me that it was just getting to the point of needing it.

@youngcameracompany 11 лет назад

Thanks for all the nice comments. Who is Prashant Gaikwad? Why does this video that I made with Projects In Metal say it is by him or her? Barry Young

@bobdyckman3600 10 лет назад

Very good video, thank You very much form a fellow metal worker :)

@SuperPeterpig 9 лет назад

I use TORMEK - wet grinding wheel - never burn and keeps the perfect angle AND gives me 4 faceted bits - not 2 (chisel pointed) - AND you can touch the stone and it will not harm you as it's rotation is very slow. To sharpen a drill bit by hand takes years of practice IF ! That's why some bits have more facets than a diamond ! AND with TORMEK - no need for safety glasses !

@ProjectsInMetal 12 лет назад

Thanks!

@faragamankara5551 6 лет назад

very nice teaching,my engineer teacher in DMG co teach me like you.thank you

@derekrobbens5355 6 лет назад

I can see at least five facets or are they not a problem

@eastendguy485 3 года назад

Barry, you never say what the angle is! Apparently, it varies with the material you are cutting!

@MegaLostOne 3 года назад

118 degree's is what the gauge is supposed to be, if drilling hardened metals or thin metals I go for 135 degree.

@dylpykle69 10 лет назад

what is he dunking it in? just water to cool it?

@lukemain4222 7 лет назад

dylpykle69 Yeah

@literoadie3502 7 лет назад

And he is just dunking it so it wont burn him. Drills are made of high-speed steel which means they will become too hot to hold way before any overheating can occur.

@NMranchhand 7 лет назад

Yes, water. If the drill tip gets too hot, as indicated by its color (blue at about 600F) it will loose its hardness and be unable to cut through other steels and be useless. The steel the drill is made of is shaped while soft then heated cherry red (about 2200F) and plunged into cold water to make it much harder than all other steels. But then it was very brittle, so it was baked in an oven at 400F for about 20 min. to "draw" some of that hardness out of it in exchange for some flexibility, leaving it both very hard but also durable: tempered steel. That process would have to be repeated in its entirety to save the drill if he were to get it too hot. Alternatively, he could just grind off all the parts that turned blue but the it's like grinding your pencils so short until there's little point left (pun intended).
